LNC2V183MTEJ

The LNC2V183MTEJ is a screw-terminal (stud bolt mount) aluminum electrolytic capacitor from Nichicon's LNC series, offering 18,000 µF capacitance at a 350 V rating. It is designed for industrial power electronics where high ripple handling and long load life under elevated temperature are required.

Typical use cases include inverter circuitry, industrial power supplies and regenerative/motor drive applications that demand compact energy storage, high-frequency charge–discharge capability, and sustained performance up to 85°C.

Key Features

• High Capacitance & Voltage: 18,000 µF capacitance rated at 350 V provides substantial DC energy storage for power bus and smoothing applications.
• High Ripple Current Handling: Supports 39.2 A at 120 Hz (low frequency) and 54.88 A at 100 kHz (high frequency), enabling use with heavy ripple and high-speed charge–discharge loads.
• Long Load Life: Rated endurance of 5,000 hours at 85°C with applied rated ripple current, supporting sustained operation under elevated temperature and ripple stress.
• Thermal & Environmental Range: Operating temperature range from -40°C to +85°C and RoHS compliance for regulatory alignment.
• Electrical Characteristics: Capacitance tolerance ±20%, tangent of loss angle (tan δ) 0.2 (measured at 20°C, 120 Hz), and leakage current up to 5,000 µA.
• Robust Mechanical Package: Stud bolt mount, radial can with screw terminals (φ90 × 165 mm), designed for secure installation in industrial assemblies.
• Charge–Discharge Endurance: Specified endurance for repetitive charge–discharge behavior (data supports durability under repeated cycles).

Typical Applications

• Industrial Drives & Inverters: Energy storage and DC link smoothing for inverter circuitry in industrial motor controllers and drive systems.
• Power Supplies: Bulk capacitance and ripple suppression in industrial power supplies that require high ripple-current capability at 350 V.
• Regenerative Motor Control: Handling high-frequency regenerative voltages for AC servomotors and general inverter-based motor control applications.
• High-Speed Charge–Discharge Systems: Systems with rapid charge–discharge cycles where capacity, ripple performance and endurance are critical.

Unique Advantages

• High ripple-current capacity: Measurable 39.2 A (120 Hz) and 54.88 A (100 kHz) ratings reduce thermal stress and extend service life in high-ripple environments.
• Significant energy density: 18,000 µF at 350 V provides large DC bus energy in a compact screw-terminal can for robust power smoothing.
• Designed for long service under load: 5,000-hour rated life at 85°C under applied ripple current supports demanding industrial duty cycles.
• Stud bolt mounting: Screw-terminal stud mount ensures secure electrical and mechanical connection in heavy-current assemblies.
• Wide operating range: −40°C to +85°C operational range accommodates varied industrial ambient conditions.
• Regulatory compliance: RoHS-compliant construction for simplified regulatory handling in assemblies.
